Determine the CW Weight of a Call Sign
This call weight calculator will show you the time taken to send a call.
The higher the number (greater weight), the longer it will take to send.
Enter the Call you wish to get the weight for below.
You may also change the speed which is currently set to 13 WPM.
Time to send at WPM is 0 seconds. **
*An extra three unit character space has been added to the call to be consistent
with the standard adopted by other websites showing call sign weight.
**NOTE - The extra three units are not used in the "Time to Send" Calculation.
